The warning "According to the "Network Security Law" and other laws and regulations, please complete the real-name authentication. Please update or re-download the latest APP version in time, click the submit information below, and we will have someone to review it, thank you for your patience." is an error that can pop up during Weidian account registration.
First, you should follow our general instructions to logging into Weidian and getting the SMS text message verification code.
If that doesn't work, it sounds like they want you to use the mobile app to register, and that you have to provide government id. I personally wouldn't like to provide my government id, but thankfully with a few tools you don't need a Weidian login.
